Optional 12 plate MAX LOCK friction disc upgrade
Far superior to other friction disc because they have both radial the spiral grooves for improved lubrication and cooling. Think of them like vented rotor brakes vs. solid rotor brakes, they simply outlast anything that we have tried over the years.
Optional HD billet side cover
More material in critical areas and larger corner radii makes the new side cover very stout. This increased rigidity eliminates deflection of the factory differential housing, keeping the ring & pinion gear running perpendicular to one another even during the harshest of clutch dumps.
Optional oil sight glass rear cover
A nice solution that allows you to easily add the additional correct amount of oil which will keep your front pinion bearing from running hot and ruining your day. New oil sight covers have a fill line engraved on the cover. Oil capacity is increased approximately 50%.
